Description

Technical Field

[0002] At present, existing beverage machines on the market, especially cocktail machines, usually use solenoid valves to control the opening and closing of beverage pipelines. When a cocktail contains 5 to 6 different types of beverages, 5 to 6 solenoid valves are required to control the opening and closing of the corresponding beverage pipelines. That is to say, the current valve is a one-way valve. For the scene of multiple beverage supply, multiple one-way valves need to be set. For example, the Chinese patent with publication number CN103062451A discloses a one-way valve, the upper end of the valve body is an upper interface, the lower end is a lower interface, a partition plate is provided in the valve body, a water outlet is provided on the partition plate, and a one-way valve is installed at the water outlet. The one-way valve is provided with a guide rod, a spring, and a sealing gasket. It can be seen that the function of the one-way valve is relatively single. If the beverage machine adopts a one-way valve, more connectors and connecting pipes are required inside the beverage machine, which is easy to cause problems such as wrong pipe connection during assembly, resulting in a relatively complex internal structure and assembly of the beverage machine, high manufacturing cost, and large space occupation.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model embodiment provides a multi-channel valve group. Figures 1 to 10 As shown, the multi-channel valve group includes a driving member 1, a valve body 2 and a valve core 3. The valve body 2 includes a valve seat 21 and a valve cover 22 that are interlocked, a valve cavity is formed between the valve seat 21 and the valve cover 22, a plurality of inlet channels 211 that are connected to the valve cavity and are independent are provided on the valve seat 21, and a discharge port 23 that is connected to the valve cavity is provided on the valve cover 22 or the valve seat 21. The valve core 3 is arranged in the valve cavity and connected to the driving member 1, and a communication channel 31 that is connected to the discharge port 23 is formed on the valve core 3. The valve core 3 is used to rotate under the drive of the driving member 1 so that the communication channel 31 is connected to one of the multiple inlet channels 211, so that the fluid that enters the valve cavity through one of the multiple inlet channels 211 is discharged to the discharge port 23 through the communication channel 31.

[0031] Figures 1 to 6 FIG. 2 is a schematic diagram of a multi-channel valve group in accordance with an embodiment 1. The discharge port 23 of the multi-channel valve group in accordance with the embodiment 1 is arranged on the valve seat 21. Figures 7 to 10 2 is a schematic diagram of a multi-channel valve group in the second embodiment, wherein the discharge port 23 of the multi-channel valve group in the second embodiment is arranged on the valve cover 22. Figure 6 and Figure 8 The arrow direction shown in the figure is the flow direction of the fluid.

[0032] The driving member 1 may be arranged outside the valve body 2, and drives the valve core 3 in the valve body 2 to rotate around its own rotation axis in a clockwise direction or a counterclockwise direction.

[0033] The plurality of inlet channels 211 may be arranged at intervals on a side of the valve seat 21 away from the valve cover 22 and located at the outer peripheral edge of the valve seat 21. The plurality of inlet channels 211 may be connected to different types of fluids, respectively, and the specific number of the inlet channels 211 may be determined according to actual needs. Figure 3The number of inlet channels 211 shown in the figure is 6 and is only an example. The driving member 1 can drive the valve core 3 to rotate in a clockwise direction or a counterclockwise direction. When the valve core 3 rotates to connect the communication channel 31 on the valve core 3 with one of the multiple inlet channels 211, the fluid can be discharged from the inlet channel 211 and the communication channel 31 to the discharge port 23 in sequence. Then the driving member 1 can drive the valve core 3 to continue to rotate so that the communication channel 31 on the valve core 3 is connected with another one of the multiple inlet channels 211, thereby realizing the addition of different types of fluids.

[0034] The valve core 3 may be formed with a connecting portion 32 on one side facing the driving member 1. The connecting portion 32 may have a first end 321 and a second end 322 connected in a vertical direction. The valve cover 22 may be formed with a through hole adapted to the first end 321. The first end 321 is penetrated through the valve cover 22 through the through hole so that the valve core 3 and the valve cover 22 can be rotatably connected. The second end 322 may be connected to the driving member 1 so that the driving member 1 can drive the valve core 3 to rotate.

[0035] The valve seat 21 and the valve cover 22 can be fixed by means of a snap connection, a threaded connection or a screw connection, which is not specifically limited in this application. For example, the outer edges of the valve seat 21 and the valve cover 22 can have matching screw holes, and the two are fixed by screws.

[0036] The outer peripheral edge of the valve seat 21 facing the valve cover 22 may be provided with a groove, and a sealing ring may be provided in the groove, so that leakage of the valve body 2 can be avoided.

[0037] The valve seat 21 may also be provided with a closing surface. When the driving member 1 drives the connecting channel 31 on the valve core 3 to rotate to the closing surface, the multi-channel valve group may close all external channels.

[0038] The above-mentioned fluid can be liquid or gas, etc. All fluids with fluidity are within the scope of this application, and this application does not make specific limitations on this.

[0039] The utility model can drive the valve core 3 to rotate through the driving member 1, so that the communication channel 31 on the valve core 3 can be connected to one of the multiple inlet channels 211 respectively, and different types of fluids can flow into the valve cavity through different inlet channels 211 and be discharged from the discharge port 23. In this way, while using the multi-channel valve group to realize the free switching of different types of fluids into the valve cavity and discharge through the discharge port 23, the internal structure of the multi-channel valve group is simplified, and the practicality and convenience of the multi-channel valve group are effectively improved. And when the multi-channel valve group is used in equipment such as beverage machines, it can effectively reduce the space occupied by the valve group, and reduce the manufacturing cost and failure rate of beverage preparation equipment such as beverage machines.

[0040] In some embodiments, Figure 3 and Figure 4 As shown, the multi-channel valve group also includes a valve plate 4, one side of the valve plate 4 is arranged to fit the valve core 3, and the other side is arranged to fit the inner wall surface of the valve seat 21. The valve plate 4 is provided with first connecting holes 41 which are arranged one by one corresponding to the entrance channels 211. The valve core 3 is used to rotate so that the connecting channel 31 is connected to one of the multiple first connecting holes 41.

[0041] In some embodiments, by setting a valve plate 4 between the valve seat 21 and the valve core 3, while ensuring that different types of fluids can be discharged in sequence as the valve plate 4 rotates, it can also ensure that the valve seat 21 and the valve core 3 are more closely connected, effectively improving the reliability and sealing of the multi-channel valve group.

[0042] The valve core 3 and the valve plate 4, as well as the valve plate 4 and the valve seat 21, may have smooth surfaces and fit closely to each other. Optionally, the valve core 3 and / or the valve plate 4 may be made of high-strength, wear-resistant materials such as ceramics, metals or plastics.

[0043] The above-mentioned multiple first connecting holes 41 can correspond to multiple inlet channels 211 respectively, and the diameter of the above-mentioned first connecting holes 41 can be greater than or equal to the diameter of the corresponding inlet channel 211 to avoid spillage of the fluid when it flows from the inlet channel 211 to the first connecting holes 41.

[0044] When the driving member 1 drives the valve core 3 to rotate, the connecting channel 31 on the valve core 3 can be respectively connected with the first connecting hole 41 on the valve plate 4, so that the fluid can be discharged to the discharge port 23 through the inlet channel 211, the first connecting hole 41 and the connecting channel 31 in sequence.

[0045] In some embodiments, Figures 1 to 5 As shown, the discharge port 23 is provided on the valve seat 21 , and the valve plate 4 is provided with a second communication hole 42 which communicates with the discharge port 23 .

[0046] In the above embodiment, the discharge port 23 is arranged on the valve seat 21 and the fluid is discharged through the second connecting hole 42 on the valve plate 4, which effectively ensures the compact structure and reasonable layout of the multi-channel valve group.

[0047] The above-mentioned discharge port 23 can be arranged on a side of the valve seat 21 away from the valve cover 22 and located at the outer peripheral edge of the valve seat 21, or located at the center of the valve seat 21, and the present application does not make any specific limitation on this.

[0048] The second connecting hole 42 can be arranged corresponding to the discharge port 23 , and the diameter of the second connecting hole 42 can be less than or equal to the diameter of the discharge port 23 . After the fluid passes through the inlet channel 211 , the first connecting hole 41 and the connecting channel 31 in sequence, it can be discharged to the discharge port 23 through the second connecting hole 42 .

[0049] In some embodiments, Figure 3 As shown, the connecting channel 31 includes a first hole body 311, a connecting groove 312 and a second hole body 313. The first hole body 311 is connected to the second hole body 313 through the connecting groove 312. The first hole body 311 is arranged corresponding to the first connecting hole 41, and the second hole body 313 is arranged corresponding to the second connecting hole 42.

[0050] In the above embodiment, through the communication and cooperation between the first hole body 311, the connecting groove 312 and the second hole body 313, the fluid can be guided from the first connecting hole 41 to the second connecting hole 42, effectively ensuring the sealing of the fluid when flowing in the valve core 3. In addition, the first hole body 311, the connecting groove 312 and the second hole body 313 can be embedded in or penetrate the surface of the valve core 3, effectively reducing the thickness of the valve core 3, thereby reducing the overall thickness of the valve body 2.

[0051] like Figure 6 As shown, when the driving member 1 drives the valve core 3 to rotate, the first hole body 311 can rotate with the valve core 3 to correspond to multiple first connecting holes 41 respectively, and the fluid can flow to the first hole body 311 through the inlet channel 211 and the first connecting hole 41 in sequence, and then be discharged to the second connecting hole 42 through the connecting groove 312 and the second hole body 313.

[0052] The above-mentioned first hole body 311, connecting groove 312 and second hole body 313 can be embedded in the surface of the valve core 3 close to the valve plate 4, or can penetrate the surface of the valve core 3 to form a through groove. The size and shape of the above-mentioned connecting groove 312 itself are not specifically limited. Any groove body that can connect the first hole body 311 and the second hole body 313 is within the scope of this application.

[0053] In some embodiments, Figure 3 and Figure 5 As shown, a limiting block 43 is provided on the valve plate 4 , and a limiting groove 212 adapted to the limiting block 43 is provided on the valve seat 21 .

[0054] In the above embodiment, the relative rotation between the valve plate 4 and the valve seat 21 can be limited by the limiting cooperation between the limiting block 43 and the limiting groove 212, thereby preventing the valve plate 4 from rotating due to friction when the driving member 1 drives the valve core 3 to rotate, thereby causing the first connecting hole 41 on the valve plate 4 to not correspond to the entrance channel 211, thereby effectively reducing the failure rate of the multi-channel valve group and ensuring the reliability of the multi-channel valve group.

[0055] The above-mentioned limit block 43 can be a protrusion formed on the side of the valve plate 4 close to the valve seat 21. The above-mentioned protrusion and the valve plate 4 can be detachably connected or integrally formed, and the present application does not make any specific limitation on this.

[0056] The above-mentioned limiting groove 212 can be determined as a groove or a through groove according to the thickness of the protrusion. The present application does not make any specific limitation on this. The limiting groove 212 and the limiting block 43 can be adapted to each other.

[0057] In some embodiments, Figure 7 , Figure 8 and Fig. 9 As shown, the discharge port 23 is disposed on the valve cover 22 , and a receiving cavity 221 for receiving fluid is formed on the valve cover 22 . The discharge port 23 communicates with the communication channel 31 through the receiving cavity 221 .

[0058] In the above embodiment, the fluid flowing into the valve body 2 can be collected in the accommodating chamber 221 and then discharged from the discharge port 23 on the valve cover 22. Since the accommodating chamber 221 has a large storage space, it can avoid the situation where the flow is interrupted due to insufficient flow when discharging the fluid.

[0059] The outlet 23 may be disposed on a side of the valve cover 22 away from the valve seat 21, and the direction of the outlet 23 may be determined according to actual use requirements. Figure 7 As shown, the direction of the outlet 23 may be perpendicular to the length direction of the inlet channel 211. Alternatively, the direction of the outlet 23 may be parallel to the length direction of the inlet channel 211, which is not specifically limited in the present application.

[0060] The accommodating cavity 221 may be annular and disposed on the inner wall of the valve cover 22 facing the valve seat 21 . The fluid flowing in through the inlet channel 211 and the connecting channel 31 in sequence may be collected in the accommodating cavity 221 and then discharged from the discharge port 23 on the valve cover 22 .

[0061] In some embodiments, Figure 8 As shown, an annular groove is formed on the valve cover 22, and the accommodating chamber 221 includes a first annular chamber 222 located on the inner side of the annular groove and a second annular chamber 223 located on the outer side of the annular groove, the second annular chamber 223 is communicated with the discharge port 23, the communicating channel 31 is communicated with the first annular chamber 222, and a third communicating hole 224 is provided on the annular groove, so that the communicating channel 31 is communicated with the discharge port 23 via the first annular chamber 222, the third communicating hole 224 and the second annular chamber 223 in sequence.

[0062] In the above embodiment, the first annular cavity 222 and the second annular cavity 223 can make the fluid evenly distributed in the valve body 2, effectively ensuring the stability of the fluid, and can also reduce the turbulence phenomenon in the fluid flow, making the fluid flow more stable, and effectively improving the control accuracy of the multi-channel valve group.

[0063] like Fig.10 As shown, the fluid can flow into the first annular cavity 222 from the inlet channel 211 and the connecting channel 31 in sequence. When the fluid fills the first annular cavity 222, it can overflow to the second annular cavity 223 through the third connecting hole 224, and then be discharged from the discharge port 23 connected to the second annular cavity 223.

[0064] The size of the third communication holes 224 can be determined according to actual use requirements. When the discharge efficiency of the multi-channel valve group needs to be improved, the size and / or number of the third communication holes 224 can be increased. Conversely, when the discharge efficiency of the multi-channel valve group needs to be reduced, the size and / or number of the third communication holes 224 can be reduced.

[0065] In some embodiments, Figures 1 to 4 As shown, the multi-channel valve group also includes a transmission assembly 5, which includes a meshing driving wheel 51 and a driven wheel 52, the driving wheel 51 is connected to the output shaft 11 of the driving member 1, and the driven wheel 52 is connected to the valve core 3, so that the valve core 3 is connected to the driving member 1 via the transmission assembly 5.

[0066] In the above embodiment, through the coordinated transmission between the mutually meshing driving wheel 51 and the driven wheel 52, the diameters of the driving wheel 51 and the driven wheel 52 can be adjusted according to different usage scenarios or usage requirements, and then the driving force applied by the driving member 1 to the valve core 3 can be adjusted to make the valve core 3 have different rotation speeds, thereby effectively improving the practicality and universality of the multi-channel valve group.

[0067] The driving wheel 51 can be sleeved on the outside of the output shaft 11 of the driving member 1, and the driven wheel 52 can be sleeved on the outside of the second end 322 of the connecting portion 32. The gear teeth of the driving wheel 51 and the gear teeth of the driven wheel 52 are meshed with each other, so that the driving member 1 can drive the valve core 3 to rotate through the driving wheel 51 and the driven wheel 52.

[0068] The sizes of the driving wheel 51 and the driven wheel 52 can be determined according to the actual transmission ratio. For example, when the rotation speed of the valve core 3 needs to be increased, the diameter of the driving tooth can be increased and the diameter of the driven tooth can be reduced. Conversely, when the rotation speed of the valve core 3 needs to be reduced, the diameter of the driving tooth can be reduced and the diameter of the driven tooth can be increased.

[0069] The output shaft 11 may be in a square or D-shaped shape, etc., and a through hole matching the shape of the output shaft 11 is provided at the rotation center of the driving wheel 51, so that the output shaft 11 and the driving wheel 51 can be tightly connected, effectively improving the rotation efficiency of the driving wheel 51. It is understandable that the second end 322 of the connecting portion 32 and the through hole of the driven wheel 52 matching the second end 322 may also adopt the above-mentioned shape, thereby improving the rotation efficiency of the driven wheel 52.

[0070] In some other embodiments, such as Figures 7 to 10 As shown, the multi-channel valve group may not be provided with the transmission assembly 5, and the driving member 1 may be directly connected to the second end 322 of the connecting portion 32, thereby driving the rotation of the valve core 3. Alternatively, the user may manually rotate the second end 322 of the connecting portion 32 so that the valve core 3 can rotate in a clockwise direction or a counterclockwise direction, and this application does not make specific limitations on this.

[0071] The utility model also provides a beverage preparation device, which comprises the multi-channel valve group as mentioned above.

[0072] The beverage preparation device using the multi-channel valve group can drive the valve core 3 to rotate through the driving member 1, so that the communication channel 31 on the valve core 3 can be respectively connected with one of the multiple inlet channels 211, and different types of fluids can flow into the valve cavity through different inlet channels 211 and be discharged from the discharge port 23. In this way, while the multi-channel valve group can be used to realize the free switching of different types of fluids into the valve cavity and discharged through the discharge port 23, the internal structure of the multi-channel valve group is simplified, effectively improving the practicality and convenience of the multi-channel valve group.

[0073] In some embodiments, Fig.11 As shown, the beverage preparation device further comprises a flow meter 6 and a pump body 7. The pump body 7 is connected to the discharge port 23 through a discharge pipe to apply a suction force to the discharge port 23. The flow meter 6 is arranged on the discharge pipe.

[0074] In the above embodiment, the pump body 7 connected to the discharge port 23 can effectively improve the discharge efficiency of the fluid of the multi-channel valve group, and the flow meter 6 arranged on the discharge pipeline can monitor the amount of fluid discharged each time, thereby ensuring the appropriate ratio of the beverage, effectively improving the practicality and preparation efficiency of the beverage preparation equipment.

[0075] The beverage preparation device may further include a control chip. The control chip may send a control signal to the driving member 1 so that the driving member 1 drives the valve core 3 to rotate.
